This well drilling cost calculator gives you a rough low-to-high planning range for a domestic well in Tulare County, CA, whether you are drilling new or deepening an existing well. It uses no hidden pricing. Every rate comes from the labelled ranges in our well drilling cost guide for Tulare County, plus the pump replacement ranges in our pump repair cost guide.
This is an estimate, not a quote. It multiplies broad planning ranges by the depth and options you enter. Your real price depends on your property, the ground, the casing and the driller. Use the result to check whether bids look reasonable, then request written quotes from independent local companies with the form on this page. For a decision on whether to deepen or replace, read deepen your well or drill a new one.

Where the numbers come from
All rates are planning ranges already published on our own pages. We added nothing from outside them.
- Drilling and casing, new well: roughly $30 to $70 per foot, installed, from the cost guide.
- Pump system, new well: roughly $1,500 to $5,000 overall. The guide's example budgets show $1,500 to $3,500 for a 200 ft well, $2,000 to $4,000 for 300 ft and $3,000 to $5,000 for 500 ft. The calculator picks the closest one: up to 250 ft, up to 400 ft, or deeper. Those cut-offs are our simplification, and so is applying the 500 ft figure to anything deeper.
- Pressure tank and controls: roughly $300 to $1,500 at any depth, as in the guide's examples.
- Deepening: roughly $35 to $85 per foot of added depth, from the cost guide. Here you enter the feet added, not the total depth.
- Pump work when deepening: the pump repair cost guide puts submersible pump replacement at roughly $1,000 to $2,500 for common jobs and $3,000 to $5,700 or more for deep or complex ones. Treating those as the two choices is our split, not a sourced one, and “or more” means the real high end can be above the number shown.
- Contingency: 10 to 20 percent of the subtotal, as the cost guide suggests for its example budgets.
As a check, the calculator reproduces the guide's three example totals (about $7,800 to $19,000 at 200 ft, $11,300 to $26,500 at 300 ft and $18,300 to $41,500 at 500 ft) when the pump and tank are on and contingency is off.
What adds nothing to the estimate
These lines have no published figure we can use, so the calculator adds $0 for each. That does not mean they are free.
- County permit fee. The cost guide says we could not verify the current amount. Ask Tulare County Environmental Health, and see the well permit guide.
- Electrical, trenching and plumbing to the house. The guide says it varies widely and is often a few thousand dollars on a long run, with no range to multiply.
- Water testing and disinfection, and any water treatment. See well water testing.
- Destroying an old well, cleanup, and a camera inspection before deepening.
- A dry or low-yield hole. No one can guarantee water at a planned depth. Ask each driller in writing how that is handled.
How to use the result
- Run it at a shallower and a deeper depth. Depth is the biggest unknown, so the gap shows how much risk sits in your budget.
- Ask each driller for an itemized written quote with depth, casing, pump, tank and exclusions, so you can compare line by line.
- If a bid is far below the low end, ask what it leaves out and check the license. If it is far above the high end, ask what is driving it.
- Read how to choose a well driller, then use the form on this page to ask independent local companies for quotes.
Frequently asked questions
How accurate is this well drilling cost calculator?
It is a planning tool, not a quote. It multiplies the broad ranges published in our Tulare County cost guide by the depth and options you enter. Real prices depend on your site, the formation, casing, driller availability and what a quote includes, so use the result to sanity-check bids, then get written quotes.
Why is the range so wide?
Because the published inputs are wide. Per-foot prices differ between national guides, a statewide table and a Central Valley example, and pump systems vary with depth and demand. A wide range is more honest than one number computed without seeing your property.
What does the estimate leave out?
The county permit fee (we could not verify the current amount), electrical, trenching and plumbing to the house, water testing and disinfection, water treatment, destroying an old well, and any cost the guides give no range for. The result lists which of these apply to your choices.
Can it tell me how deep my well needs to be?
No. Depth depends on your location and local groundwater, and no one can promise water at a planned depth. A USGS summary says domestic wells in this area are typically drilled to roughly 150 to 500 feet. A driller can estimate your depth from nearby well records.
